For optimal strength and thermal performance, use Tubelite's 14000 Series Storefront Framing, a flush-glazed system for use on storefront and low-rise applications.
Framing is available in standard non-thermal and thermal members with 2" x 4 1/2" profiles and a 1/2" bite for use with glass or panels up to 1 1/8" thick.
Extra-heavy intermediate verticals are available for high performance against strong windloads.
